1. I need to be efficient, angular discretization
•
Acuros uses the first scatter source method
so the photon spectrum exiting a source needs
to be known
•
Acuros uses Triangular-Chebyshev quadrature sets for angular discretization and the
integration for the generation of the scattering source
•
The angular discretization scheme is adaptive with S
N
order
ranging from N=4 (24 discrete directions) to 30 (960 discrete directions) varying both
within an energy group (g
→
g) and between energy groups (g
→
g’)
Guess which energies are given larger N …!
